Eddy Current Separators

The Eddy Current Separator (ECS) uses a high‑speed magnetic rotor to generate repulsive magnetic forces that separate non‑ferrous metals (like aluminium, copper, zinc) from non‑conductive materials in recycling streams. It’s commonly integrated with a drum magnet that first removes ferrous metals.

Bunting offers four ECS models tailored for different particle sizes and applications:

• High‑Intensity Eccentric (HIE) — for small non‑ferrous metals down to 3 mm

• High‑Intensity Concentric (HIC) — for small non‑ferrous metals down to 10 mm

• R‑Type ECS — for general use, non‑ferrous metals above 20 mm

• Can Sorter (CS) ECS — cost‑efficient option designed for recovering aluminium cans

ECS units consist of a two‑pulley conveyor. A non‑metallic rotor cover houses an independently spinning magnetic rotor. As feed material enters the magnetic zone, changing polarity induces eddy currents in conductive particles, generating a repelling magnetic field that deflects non‑ferrous metals. A strategically placed splitter then separates them from the non‑metallic fraction. Rotor speed is matched to pole count and application.

The HIC model features a cantilever jacking system beneath the hinge frame, allowing one person to lift and hold the conveyor from one side. After drive belt removal, the main belt can be easily and quickly replaced without removing the rotor—minimizing downtime and simplifying maintenance.

• Recover non‑ferrous metals from shredded cars, aluminium cans, WEEE, etc.

• Remove non‑ferrous contaminants from cullet, plastics, woodchip and other waste materials
  Applications span metal recycling, glass re‑melting, plastics reuse, wood processing, and waste-to-energy operations.
